I'm trying to upgrade ovirt 3.6.3 to 4.0, but engine-setup complaints about
upgrading from incompatible version 3.3
I see in the engine-setup log that vds_groups table is checked to determine
the compatibility version. The logs shows that engine-setup detects 2 clusters
versions: 3.3 and 3.6. Indeed, there is 2 clusters registered in the table:
"cluster-3.6" and "Default"
"Cluster-3.6" (version 3.6) is the only cluster in DC in my ovirt setup.
"Default" (version 3.3) should be a cluster that surely I deleted in a past
upgrade.
Why a cluster named "Default" (with compatibility version 3.3) is still present
in vds_group table? Cluster "Default" isn't displayed anywhere in the web
interface.
It looks like a bug to me. The cluster should be either missing in the
database or present in the web interface.
Could you please provide us more details about the problem? It might
help us to investigate the issue if you could do the following:
- Install ovirt-engine-webadmin-portal-debuginfo package.
- Restart Engine.
- Go to the main Clusters tab.
- Refresh the page in your browser.
- Send us the parts of engine.log and ui.log corresponding to the
refresh action.
Any clue to solve this issue?
As a workaround, if you are sure you don't have anything in Default
cluster, you may try to set compatibility_version to "3.6" for "Default"
cluster in vds_groups database table.
Hi Milan:
I solved the issue. I connected through ovirt-shell. The shell listed
the two clusters and let me to delete the 3.3 "ghost" cluster.
I don't know why this cluster was visible by ovirt-shell but not by WebUI.
I migrated the engine from Centos 6 to Centos 7 in a new VM. I will try
to install ovirt-engine-webadmin-portal-debuginfo in the old engine VM
(I took a VM snapshot previously to delete the 3.3 cluster) and send
you the debug info.
Thanks for your help.
Federico
